The fuzz tester keeps failing with this file:
    /home/wireshark/menagerie/menagerie/6550-iPhone_connection_and_SSH_session.cap:
 ERROR
Processing failed.  Capture info follows:
  Output file: /dev/shm/buildbot/clangcodeanalysis/menagerie-fuzz/fuzz-2012-03-02-17845.pcap
stderr follows:
tshark: The file "/dev/shm/buildbot/clangcodeanalysis/menagerie-fuzz/fuzz-2012-03-02-17845.pcap" appears to be damaged or corrupt.
(pcapng: interface index 1 is not less than interface count 1.)
The source file itself is fine (well it no longer aborts for me after 
r41325), but running it through the fuzz tester fails every time.  Looks 
like editcap needs some PCAPNG smarts to avoid corrupting the non-packet 
parts.  (Or Wiretap needs to not give the non-packet parts to editcap.)
